What's the weirdest cookbook you own?

First off, I admit to cookbook addiction---are there meetings for this sort of thing--ha! I have cookbooks for: cooking for cats (have no pets), cowboys, cooking with Ziggy, Coca-Cola, computer hackers, cooking with ketchup & potato chips...the pile of titles & books go on & on :) What is your weirdest cookbook & do you actually prepare any of the recipes?
